Recorded 1885–1973 · United States
Guilford was most popular in 1923, when 22 American babies were given the name — ranking #3,302 that year. It was not recorded in 2025. Across 1880–2025 the Social Security Administration has recorded 589 people named Guilford.
Across the whole record Guilford is a boy’s name — 0.0% of the 589 Americans given it were girls and 100.0% were boys.
Counted from every US birth the Social Security Administration recorded under this name, so it reflects use rather than opinion. A name given to fewer than five babies of one sex in a year is withheld at source and is not counted.
